Biography
Mary of Austria was born in Brussels, Habsburg Netherlands in 1505, the daughter of Philip I of Castile and Joanna of Castile. She married King Louis II of Hungary in 1515, and they had a happy marriage until he died in battle with the Ottomans at the Battle of Mohacs in 1526, not producing any children with her. She governed Hungary as regent for her brother, the future Emperor Ferdinand I of Germany, and she was sent to the Spanish Netherlands in 1531 by her eldest brother, Charles V, in order to serve as governor there. She faced riots and a difficult relationship with the emperor, and, despite her hatred of governing, she created unity between the provinces. She finally resigned in 1555 and died in Cigales, Spain in 1558 at the age of 53.
